Description
Technical field
The present invention relates to a kind of explosive motor with centrifugal force pendulum device, which has at least one surround
The rotatable pendulum bracket of rotation axis（pendulum mass carrier）And at least one pendulum pair, the pendulum is to bag
Two are included to be movably disposed on pendulum bracket, relative to each other and have the pendulum of certain distance with rotation axis.This hair
It is bright further to a kind of method, it is used for the centrifugal force pendulum device for manufacturing such a explosive motor.
Background technology
In the construction and design of motor vehicles and explosive motor, the attention to vibration is growing day by day.Especially, at present
Having made influences the trial of the noise as caused by explosive motor.The motivation of this development is recognized from true to one
Know, i.e. the purchase decision of consumer is influenced by explosive motor and vehicle noise to a certain extent, particularly from comfortable
From the point of view of angle.Transmission by the structure-borne noise of engine mount portions to car body is to have spy for the driving comfort of the sense of hearing
Not important meaning.
The phenomenon of vibration by briefly illustrating with reference to the example of crank gear and bent axle in detail.
Bent axle forms concussion system together with the engine components being coupled to thereon.Bent axle passes through by being coupled to indivedual bent axles
The rotatory force changed over time that the connecting rod of pin is transferred to bent axle is excited to produce rotation concussion.The rotation vibrations production of bent axle
Raw noise is transmitted to car body and explosive motor by structureborne noise radiation and structure-borne noise.If bent axle its from
It is excited in right frequency range, then big rotation vibration amplitude can be produced, and result even in fatigue fracture.It is newest to consider
Point out that vibration has an impact similarly for component strength.
The rotation concussion of bent axle causes the rotary speed of explosive motor to be shaken, and again by timing transmission（timing
drive）Or camshaft drive is transferred to camshaft, camshaft is similarly a vibroseis in itself, it can be further
System in excite vibrations, particularly valve gear.By by bent shaft-driven traction drive to other auxiliary units
Vibration transmission is equally possible.In addition, the concussion of bent axle is transferred to transmission system, via it by onwards transmission to speed changer
With drive shaft and until the tire of vehicle,.
In order to reduce rotary speed fluctuation, the quality of vibroseis on bent axle by disposing flywheel to be increased.As more
Big quality as a result, the system has increased inertia.The rotary motion of bent axle becomes more homogeneous.
If generally side is fixed on bent axle and opposite side is fixed on speed changer by clutch and flown
Wheel is double mass flywheel（dual-mass flywheel）Form, then flywheel additionally there is shock damping device, its
Reduce the rotation concussion between clutch and driving device.
In order to suppress the concussion of the rotation in bent axle and transmission system, rotation shock damping device, i.e. torsion damping can be equipped with
Device.Quality as damper is relative to the relative motion of bent axle as a result, a part of rotation vibration energy passes through fricting movement
To dissipate.
So-called centrifugal force pendulum device is used as torsional damping arrangement more and more, its pendulum be not at kinetic current it
In, and the concussion with excitation is oppositely moved when excited, therefore cause abatement or the suppression of the latter.Use usual resistance
Buddhist nun's device or shock absorber, its effect only occur under specific frequency, i.e. the resonant frequency of damper.Restoring force is mainly by making
It is the adaptive shock absorber of rotary speed in contrast with the centrifugal force on pendulum come the centrifugal force pendulum device determined, it is solid
There is frequency by changing with rotary speed, because centrifugal force depends on rotary speed.Therefore, by centrifugal force pendulum device, to fixed
The absorption of firing order is possible to rather than just the absorption of fixed frequency.It has special excellent in explosive motor
Gesture, wherein centrifugal force pendulum device can adjust and fully absorb any desired excitation time for any desired firing order
Sequence.
Number of patent application is that the German Patent Application Publication of 2,006 028 556 A1 of DE10 describes such a centrifugation
Pendulum device, it is arranged in the transmission system of motor vehicles and works wherein, and for absorbing and/or suppressing transmission system
In rotation concussion.The centrifugal force pendulum device of 10 2,006 028 556 A1 of DE have can surround the rotating pendulum support of rotation axis
Frame and at least one pendulum pair, the pendulum to including two it is relative to each other, be movably disposed on pendulum bracket and
There is the pendulum of a certain distance with rotation axis.Pendulum is movably coupled to, i other words, by moving it is couple to pendulum support
Frame, pendulum have arch opening, are installed in the roller bearing on pendulum bracket and support and be oriented in the arch opening.The arch is opened
Oral area forms the track for roller bearing and is previously determined the movement of pendulum.
Fig. 1 a, 1b and 1c show the centrifugal force pendulum device of 10 2,006 028 556 A1 of DE disclosures, Fig. 1 a with simplification view
Show the centrifugal force pendulum device under so-called zero state, Fig. 1 b are the centrifugal force pendulum device of operating position and Fig. 1 c are quiet in vehicle
When only, i.e. the centrifugal force pendulum device of position when explosive motor is not run.
Shown centrifugal force pendulum device（21）With around rotation axis（22）Rotatable pendulum bracket（23）With in pendulum
Bracket（23）Upper component capable of movable installed simultaneously forms pendulum pair（24）Two pendulums（24a、24b）.Pendulum（24a、24b）With arch
Shape opening portion（26a、26b）, it is arranged relative to each other, with rotation axis（22）It is spaced apart and by being bonded on opening（26a、
26b）In pendulum bracket（23）Roller bearing pin（25a、25b）It is mounted and by active movement guides, the pendulum of Fig. 1
（24a、24b）It is also regarded as being arranged relative to each other in the background of the invention, as long as also, pendulum（24a、24b）Weight
The heart and rotation axis（22）With certain distance, pendulum（24a、24b）Just it is considered as and rotation axis（22）It is spaced apart.Arch is opened
Oral area（26a、26b）Representative is used for roller bearing pin（25a、25b）Track（26a、26b）And pendulum is therefore preset（24a、24b）
Movement.
As explosive motor is not run and vehicle is in halted state, and pendulum bracket is fixed, pendulum（24a、24b）
The position shown in Fig. 1 c can be taken and therefore form out-of-balance mass.Which results in some problems, especially when pendulum bracket
（23）When being again set at rotation, for example when explosive motor starts, and pendulum（24a、24b）In this start-up course
In the operating position shown in Fig. 1 b --- i.e. at the beginning of rotary motion --- must be initially positioned at.Increased noise occurs,
It is its result together with high stress of the pendulum bearing particularly on roller bearing pin.
In this context it should be considered that the quantity that explosive motor is started or reset is increasing, this is because car
Stop-start operation Modern Concepts, also referred to as startup/stop mode, internal combustion hair is closed in no instantaneous power demands
Motivation is to reduce fuel consumption, rather than allows its idle running.In fact, this means the explosive motor at least in stationary vehicle
It is closed.When a kind of application of stop-start operation is that traffic occurs, such as when car lane and major trunk roads congestion.In city
Under the traffic at center, stop-start operation is no longer exception but a kind of normality, goes out as uncoordinated traffic lights
Existing result.Other application is track level crossing etc..Therefore the quantity of starting process adds.
Further centrifugal force pendulum device is in the published Deutsche Bundespatent Shen of 10 2,011 105 029 A1 of Patent No. DE
Please in be described.
The content of the invention
Under the background, it is an object of the invention to provide a kind of explosive motor with centrifugal force pendulum device, with
